The 1/72nd scale Revell U-Boats have a lot of small railing parts.
These railing fit around the guns.
They really make a big difference in the detail and quality of the kit. They look complicated, but they fit very easily. The molds are very well done, there was no flash, and the parts had few connections to the sprue so they were easy to remove. They also aligned perfectly with the hull parts, which was very nice.
I used photos from this Osprey book to determine the different armaments to use on the one submarine with the quad 20 mm AA guns.
Side by side these two U-Boats look pretty awesome. U-Boats often nested together like this in port so they did not take up much room at dockside. The wooden decks are well detailed on these kits.
